Rain battered Blackthorn Manor while guests gathered for midnight séance. At precisely twelve, chandelier flickered above the great dining room. Colonel Vale raised his glass, smiling toward his assembled enemies. Then darkness swallowed every face, every whisper, every trembling hand. A gunshot cracked sharply, followed by Lady Emmeline's startled scream. When candles returned, Vale lay bleeding beside the locked conservatory. His silver key gleamed beneath fingers curled around torn velvet. No window stood open, yet muddy footprints crossed marble tiles. Detective Rowan entered quietly, carrying rainwater, suspicion, and unwelcome certainty. “Nobody leaves,” he said, studying the corpse's oddly peaceful expression.
